You mention that Calzirtite probably formed by condensation or crystallized from a refractory melt under extremely reduced conditions in the solar nebula. Do you prefer one of these formation mechanisms over the other? Also, have you found Calzirtite in any other chondrite?

Submitted by Emily Worsham on Thursday 25th June 12:18
If calzirtite was condensed, where in the condensation sequence would it be relative to major minerals and the other Zr-bearing minerals?

Any idea why previous condensation calculations have not predicted the ultrarefractory phases you list on your last slide?
